[0005] The purpose of the utility model is to provide an anti-loosening USB connector to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: an anti-loosening USB connector, comprising a main body mechanism, a protective mechanism is arranged outside the main body mechanism;

[0007] The main body mechanism includes a joint, a connecting wire is fixedly connected to the left side of the joint, a plug joint is fixedly connected to the left side of the connecting wire, springs are fixedly connected to the inner walls of the upper and lower ends of the plug joint, a locking block is fixedly connected to one end of the spring, and a receiver is movably connected inside the plug joint.

[0008] Furthermore, by inserting the receiver into the plug connector, the locking block is squeezed through the outer surface of the receiver, and then the spring is squeezed through the locking block. The contraction of the spring drives the locking block to move into the through hole opened in the upper and lower inner walls of the plug connector. When one end of the groove opened in the upper and lower surfaces of the receiver and matched with the locking block moves to the locking block, the locking block is clamped into the groove opened in the upper and lower surfaces of the receiver through the expansion and contraction of the spring. The receiver is fixed by the fit between the outer surface of the locking block and the inner wall of the groove opened in the upper and lower surfaces of the receiver, thereby achieving the effect of preventing loosening and avoiding shaking when the receiver is connected to the plug connector, thereby achieving the effects of simple structure, low cost and high popularity.

[0009] Preferably, anti-slip grooves are provided on the upper and lower surfaces of the joint.

[0010] Furthermore, the anti-slip grooves provided on the upper and lower surfaces of the connector facilitate operators to better grip the connector when plugging and unplugging it, thereby improving the convenience and safety of operation.

[0011] Preferably, through holes are provided on the upper and lower inner walls of the plug connector, and one end of the spring is fixedly connected to the through holes provided on the upper and lower inner walls of the plug connector.

[0012] Furthermore, one end of the spring is fixed inside the through hole opened on the inner walls of the upper and lower sides of the plug connector, and then the other end of the spring is fixedly connected to the locking block. The receiver is fixed by squeezing the locking block on the outer surface of the receiver when plugging and unplugging the receiver.

[0013] Preferably, the locking block is movably connected to through holes formed on the inner walls of the upper and lower sides of the plug connector.

[0014] Furthermore, when the receiver is plugged in or out, the outer surface of the receiver squeezes the locking block and the locking block squeezes the spring, and the spring contracts and drives the locking block to move into the through hole formed on the upper and lower inner walls of the plug connector to release the fixation of the receiver.

[0015] Preferably, grooves matching the locking block are formed on the upper and lower surfaces of the receiver, and the outer surface of the locking block fits with the inner walls of the grooves formed on the upper and lower surfaces of the receiver.

[0016] Furthermore, through the grooves adapted to the locking block opened on the upper and lower side surfaces of the receiver, when the receiver is inserted into the plug connector, the locking block can be squeezed through the outer surface of the receiver to squeeze the locking block spring, and the contraction of the spring drives the locking block to move toward the through hole opened on the upper and lower side inner walls of the plug connector. When one end of the grooves adapted to the locking block opened on the upper and lower side surfaces of the receiver reaches the locking block, the locking block is clamped into the grooves opened on the upper and lower side surfaces of the receiver through the expansion and contraction of the spring, and the receiver is fixed by the fit between the outer surface of the locking block and the inner wall of the grooves opened on the upper and lower side surfaces of the receiver.

[0017] Preferably, the protection mechanism includes a protective cover and an anti-interference shell.

[0018] Furthermore, by putting a protective cover on one end of the connecting wire, the connecting wire can be effectively protected from external physical damage, such as friction, bending and pulling. These actions may cause wear and tear of the connecting wire, and even cause poor contact of the internal wires. By reducing the damage to the connecting wire caused by these external factors, its service life can be extended. The anti-interference shell is a prior art and will not be described in detail here. The anti-interference shell fixedly connected to the outer surface of the plug connector can shield external electromagnetic interference: electromagnetic interference may come from various surrounding electronic devices, such as mobile phones, computers, televisions, etc. These devices will generate electromagnetic radiation when working, which may interfere with the normal operation of the receiver. The anti-interference shell can effectively absorb and reflect these electromagnetic radiations, reduce their interference with the receiver, and achieve the effect of protecting the device and extending the service life of the device.

[0019] Preferably, the protective sleeve is sleeved on one end of the connecting line, and the anti-interference shell is fixedly connected to the outer surface of the plug connector.

[0020] Furthermore, by putting a protective cover on one end of the connecting wire, the connecting wire can be effectively protected from external physical damage, such as friction, bending and pulling. These behaviors may cause wear and tear of the connecting wire, or even cause poor contact of the internal wires. By reducing the damage to the connecting wire caused by these external factors, its service life can be extended. The anti-interference shell fixedly connected to the outer surface of the plug connector can shield external electromagnetic interference: electromagnetic interference may come from various electronic devices around, such as mobile phones, computers, televisions, etc. These devices will generate electromagnetic radiation when working, which may interfere with the normal operation of the receiver. The anti-interference shell can effectively absorb and reflect these electromagnetic radiations and reduce their interference with the receiver.

[0021] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0022] First, the utility model inserts the receiver into the plug connector, and then squeezes the locking block through the outer surface of the receiver, and then squeezes the spring through the locking block. The spring contracts and drives the locking block to move into the through hole opened on the upper and lower inner walls of the plug connector. When one end of the groove opened on the upper and lower surfaces of the receiver and matched with the locking block moves to the locking block, the locking block is clamped into the groove opened on the upper and lower surfaces of the receiver through the expansion and contraction of the spring. The receiver is fixed by the outer surface of the locking block and the inner wall of the groove opened on the upper and lower surfaces of the receiver, so as to achieve the effect of preventing loosening, avoid shaking when the receiver is connected to the plug connector, and achieve the effects of simple structure, low cost and high popularity.

[0023] Second, the utility model can effectively protect the connecting wire from external physical damage, such as friction, bending and pulling, by putting a protective sleeve on one end of the connecting wire. These behaviors may cause wear and breakage of the connecting wire, and even cause poor contact of the internal wires. The damage to the connecting wire caused by these external factors is reduced, thereby extending its service life. The anti-interference shell is a prior art and will not be described in detail here. The anti-interference shell fixedly connected to the outer surface of the plug connector can shield external electromagnetic interference: electromagnetic interference may come from various surrounding electronic devices, such as mobile phones, computers, televisions, etc. These devices will generate electromagnetic radiation when working, which may interfere with the normal operation of the receiver. The anti-interference shell can effectively absorb and reflect these electromagnetic radiations, reduce their interference with the receiver, and achieve the effect of protecting the device and extending the service life of the device.
